He knows when you are sleeping, he knows when you’re awake, but now college professors even know what students are doing outside of class – like whether they’re reading their e-textbooks and taking notes.

That’s thanks to CourseSmart, a new Silicon Valley digital tracking technology that allows professors to track their students’ use of digital textbooks. The program is the ultimate academic Big Brother. According to a report in the New York Times, thanks to the program, professors “know when students are skipping pages, failing to highlight significant passages, not bothering to take notes – or simply not opening the book at all.”

CourseSmart gives each student using its text an “engagement index,” based on how many times the e-textbook was opened, for how long, how many pages were read, how much and what sort of material was highlighted, and whether notes were taken. That “engagement index” is available for professors to use to understand how individual students are responding to course material.

Not surprisingly, the program is raising some controversy, with detractors calling it creepy at best and an invasion of privacy at worst.

Even the dean of the school of business at Texas A&M acknowledged the program’s “creep factor.”

“It’s Big Brother, sort of, but with a good intent,” Tracy Hurley told the Times.

But CourseSmart’s proponents say it comes with a bevy of benefits.

The technology offers educators a powerful tool in tracking how students absorb and respond to course material. That feedback then allows professors to adjust how they present course material, tailor curricula to different sets of students, even reach out to individual students with low “engagement indexes.”

Eventually, CourseSmart says the “engagement index” data will help its publishers, including Cengage, Macmillan, Pearson, McGraw-Hill, and Wiley, design more effective e-textbook editions.

Some are predicting that today's students, who have grown up in a digital world that tracks their every move – from Facebook to Google to Amazon – won’t be bothered by CourseSmart. But from our perspective, it's not hard to feel a bit troubled by the notion that the Big Man on Campus may now be replaced by Big Brother.
